What evaporator coil means
The evaporator coil is the indoor coil, usually on top of the furnace or in the air handler, where refrigerant boils off and pulls heat and moisture out of the air.
Also called indoor coil, A-coil.
Where it matters on a HVAC job
A frozen evaporator coil usually means low airflow or low charge. Coil leaks are common on older systems, and coil replacement is labor heavy, so quote it against a full system replacement.
